Try stopping arts, or better still, stop all graphical programs (actually, reboot into a non-graphics mode (add 1 to your kernel line) for this, since sound is notorious for continuing to get in the way despite being apparently stopped). Then make sure the module is loaded and the volume is set right and run aplay [some wav file].
